Echo makes some awesome calls. I have an Echo Timber. However, they make some unbelievably loud, open-water calls called XLT. Here's a link to Echo Echo Calls - XLT Duck Calls
I also use RnT calls. My favorite call in the world is the RnT Short Barrel. It is my go-to call. It is soft in the timber and will also holler over open water. If I had to pick one call to use for all situations, it would be my Short Barrel. Here's a link to RnT Duck Calls Products - RNT Calls
Even though my RnT is my favorite call of all, the Echo XLT is - in my opinion and experience - the loudest and most versatile duck call on the market. Just my opinion though.
I can't help you with the goose calls. I am only a duck hunter. Only goose I ever killed was pure luck and just being at the right place at the right time :D.
Good luck in your picking. Let us know what you get.
